ROSS O. PIERCE, 0F MICHIGAN'l CITY., INDIANA.

NUT-LOCK.

Application mee any 1o, i917.

T0 all ywhom t may concern:

Be it known that I, Ross O. Pinnen, a citizen of the United States, residing at Michigan City, in the county of Laporte and State of Indiana, have invented new and useful Improvements in Nut-Locks, of which the following is a specification.

The present invention relates to means for locking a nut upon a bolt, and is primarily but not necessarily devised for employment in holding the nuts upon the bolts connecting the lish plates of abutting rails against accidental unscrewing.

The object of the invention is to produce a device of this character which is simple, cheap, readily arranged in operative position and which will perform the function for which it is devised with accuracy and certainty.

lith the above and other objects in view the improvement. resides in the construction, combination and arrangement of parts set forth in the following speciiieation and falling within the scope of the appended claims.

In the drawing:

Figure. l is a side elevation illustrating the applica-tion of the improvement,

Fig. 2 is a sectional view approximately on the line 2-2 of Fig. l,

Fig. 3 is a transverse sectional view approximately on the line 3-3 of Fig. 2,

Fig. l is a perspective view of the locking ring when the same is arranged to engage with the nuts or the heads of bolts, and

Fig. 5 is a plan view of the locking member before the same is bent upon itself to provide the angular construction illustrated in Fig. 4f.

Fig. 6 is an end view of the improvement.

In the application of the improvement as disclosed by the drawing I have shown two rails having abutting ends and having arranged upon their opposite sides connectingplates, bolts l having their Shanks passing` through alining threaded apertures in the plates and in the webs of the rails, and nuts 2 screwed upon the projecting ends of the Shanks of the bolts.

My improvement comprises a flat. metallic plate 3 that is provided, at a suitable distance from one of its edges with a longitudinally extending score line 4, whereby to assist in the ready bending of the plate upon the said score in order to produce an upper angular shelf portion 5 and a vertical or depending portion or body 6. The body 6,

at suitable spaced intervals, is provided with depending` fingers T, of any desired length and with depending rounded tongues S spaced a suitable distance one from each of the said fingers T and having its end directed toward the said lingers. The edge of the plate between the inner rounded periphery of the tongues 8 and the fingers 7 is rounded, as indicated by the characters 9, and the outer ends of the rounded tongues 8 are extended outwardly beyond the plane of the body 6 providing spring elements that are designed to friet-i onally contact with the inner faces of the nuts 2, when the shanks of the bolts are received between the fingers 8 and the tonguesi' and thenuts are screwed home upon the said bolts. It is to be understood that the locking member 3 is arranged upon the bolts before the nuts are screwed home upon the said bolts, and after nuts are thus applied the member 5 is bent angularly upon the score line 4; so as to contact with the edges of all of the nuts, as clearly illustrated by the drawings. The depending fingers 7 prevent the longitudinal movement of the locking member in one direction, the tongues S preventing` the longitudinal movement of the said member in an opposite direction, and the ends of the said tongues are all arranged in the same direction; that is, toward the left hand side of the plate con'iprising the locking device so that the spring` ends of the tongues will aid in retarding the movement of the nuts in an unscrewing direction, while of course, the angular member or shelf 5 provides a further means for preventing such turning of the nuts.

Having thus described the invention, what I claim is:

l. A locking device of the class described comprising a flat plate including a body having aI bendable portion, said body, at its edge opposite, that nrovided with the bendable portion being formed with spaced outwardly extending fingers and with rounded tongues spaced one from each of said fingers, said tongues having their ends terminating adjacent to the fingers and being arranged angularly in an outward direction with respect to said fingers.

2. In a locking device of the class set forth, a flat body having a longitudinal score line adjacent one of its edges whereby to permit of the metal outward of said score being bent over the body, said body at its opposite e( ge being pfovded with spaced outwe'dy extending fingers and with outwardly extending rounded tongues one arranged adjacent each of sedngers, said ngels having their outer ends terminating adjacent the espeetve tongues and extended et en angle with respect to the said tongues and to said body, and the edge of the body between seid ngers and tongues being rounded to conform With the inner 10 peripheral eontoul of the tongues.

n testimony whereof I ax my signature.
